What are the factors that affect the change of PCB “processing price
PCB fabrication belongs to OEM customers’ foundry products. Different customized products are not the same,there are few shared products. On the other hand.considering the quality aspect , some customers may designate to use a certain manufacturer. In order to meet its quality and cost control requirements, PCB fabrication has variable prices.
一．The different materials used in PCB lead to the diversity of prices.
Take normal 2L PCB as an example. The sheet materials generally include FR-4, CEM-3, etc. The sheet thickness varies from 0.6mm to 3.0mm, and the copper thickness varies from 1Oz to 3 Oz. All of these are caused by the sheet material. In terms of solder mask ink, there is also a certain price difference between ordinary thermosetting oil and photosensitive green oil, so the difference in materials causes the price diversity.
二．The differences in the production processes used by PCBs result in the diversification of prices
Different production processes will cause different costs. For example, gold-plated boards and tin-sprayed boards, the production of gongs (milling) boards and beer (punching) boards, and the use of silk-printed Different production processes will cause different costs. For example, gold-plated boards and tin-sprayed boards, the production of gongs (milling) boards and beer (punching) boards, and the use of silk-printed lines and dry film lines will cause different costs, resulting in a variety of prices.
三．The price diversity caused by the difficulty of PCB itself
Even if the material as well as the processare the same, the difficulty of the PCB itself will cause different costs. For example, there are 1000 holes on two kinds of circuit boards, and the hole diameter of one board is larger than 0.6mm and the hole diameter of the other board is smaller than 0.6mm, which will result in different drilling costs; Different, one is greater than 0.2mm, and the other is less than 0.2mm, which will also cause different production costs, because the difficult board has a higher scrap rate, which will inevitably increase the cost, and thus cause the price diversity.
四．Different customer requirements will also cause different prices
Every PCB sold in the PCB industry is customized by customers. Therefore, the quotation of the PCB board needs to be cost-calculated first. At the same time, it also needs to refer to the automatic layout calculation of the PCB computer, and the material utilization rate of the layout on the standard-size copper clad laminate is determined. Comprehensive quotation.
